[0043] The embodiments of this application disclose a method, device, electronic device and storage medium for determining abnormal line loss, which can automatically identify whether there is an abnormal line loss position and effectively avoid batch quality accidents. The following will be described in detail respectively.

[0044] Please refer to Figure 1 , Figure 1 which is an application scenario diagram of the method for determining abnormal line loss in an embodiment. As Figure 1 shown, this application scenario may include a test device 10 and a server 20, where the test device 10 is communicatively connected to the server 20. The test device may include, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers and portable wearable devices (such as smart watches, smart bracelets, smart glasses, etc.). The computer system in the test device 10 may be Windows, Linux, IOS or Unix, which is not specifically limited herein.

[0045] In an embodiment of the present application, the test device 10 is used to obtain the line loss values of each signal frequency under multiple communication systems supported by the terminal device to be detected at all stations on the production line, and send these line loss values to the server 20. In some embodiments, the test device 10 can also obtain the average line loss value of each signal frequency under the same communication system and send the average line loss value to the server 20. The test device 10 can check the line loss through the built-in detection module or establish a communication connection with an external detection device to receive the line loss value of the terminal device to be detected at the production line station sent by the external detection device. For example, the external detection device can be a combination of a vector network analyzer, a spectrum analyzer, a signal generator, and a power meter, etc. As an alternative embodiment, the built-in detection module of the test device 10 can be a gold board. As a test sample with known characteristics and standard parameters, the gold board can be integrated into the built-in detection module of the test device 10. The gold board is brought to the production line of the terminal device for power calibration. By adjusting the line loss to test and reach the power and receiving sensitivity calibrated by the gold board, the line loss of the corresponding frequency band can be obtained. In addition, the built-in detection module can also be other components or circuits with accurate line loss characteristics. For example, it can be a specially designed line loss detection chip, a sensor, etc. These components can calculate the line loss value by measuring the changes in parameters such as the intensity and frequency of the signal.

[0046] In some embodiments, the server 20 is used to receive the line loss value and the average line loss value sent by the test device 10, calculate the difference value between the average line loss value and the reference line loss value pre-stored in the server, and determine whether there is an abnormal line loss station according to the difference value. The server 20 can be a server cluster composed of multiple servers, or a single server, or a computer. For example, it can be a tower server, a rack server, a blade server, a cloud server, etc., which is not specifically limited here. The test device 10 can communicate with the server 20 through a communication network. The communication network can be a wired network or a wireless network. For example, the communication network can be a local area network (LAN), or a wide area network (WAN), such as the Internet. When the communication network is a local area network, exemplarily, the communication network can be a wireless fidelity (Wi-Fi) hotspot network, a Wi-Fi P2P network, a Bluetooth network, a zigbee network, or a near field communication (NFC) network, etc., which are short-range communication networks. When the communication network is a wide area network, exemplarily, the communication network can be a third-generation mobile communication technology network, a fourth-generation mobile communication technology network, a fifth-generation mobile communication technology network, etc.

[0047] Please refer to Figure 2 ,Figure 2 is a flowchart of a method for determining abnormal line loss in an embodiment, as Figure 2 shown, the method may include the following steps:

[0048] Step 201, obtain the line loss values of each signal frequency under multiple communication systems supported by the to-be-detected terminal device at all stations, where each station is a position set on the production line of the terminal device for detecting line loss.

[0049] In an embodiment of the present application, the to-be-detected terminal device refers to an electronic product to be produced on the production line, such as a mobile phone, a tablet computer, a smart watch, etc. The produced terminal device can perform information interaction and data transmission with the outside through different communication systems. A communication system refers to the technical standards and specifications for realizing communication. Communication systems include 2G, 3G, 4G, and 5G, etc. The to-be-detected terminal device can support multiple communication systems to meet the communication needs of different users in different scenarios. The signal frequency under a communication system refers to the frequency of the electromagnetic wave used in a specific communication system. Multiple signal frequencies can be adopted under one communication system. In some embodiments, each station is equipped with specific detection devices and tools, such as production jigs, connection wires, test jigs, etc. The detection device can be the test device 10 in the above embodiment for measuring the line loss values of each signal frequency of the to-be-detected terminal device under different communication systems. For example, a station can test the line loss values of the terminal device at multiple signal frequencies of the same communication system. The line loss value refers to the power loss generated due to factors such as line impedance and signal attenuation during signal transmission. The detected line loss values can be saved in the test device 10 or sent by the test device 10 to the server 20. In addition, the test devices and tools used in the production stage of the terminal device need to be unified to avoid excessive differences in the detected line loss values between stations due to environmental differences.

[0050] Step 202, obtain the average line loss value of each signal frequency under the same communication system according to the line loss values of each signal frequency at all stations under the same communication system.

[0051] In an embodiment of the present application, the specific method for obtaining the average line loss value of each signal frequency under the same communication system is, for example, there are several signal frequencies in the 2G communication system. The signal frequencies are represented by f1, f2, f3,... fn. There are several stations in the 2G communication system, which are respectively denoted as station 1, station 2, station 3,... station m. For the signal frequency f1, the line loss values measured at each station in the 2G communication system are respectively denoted as L 11 (indicating the line loss value of the signal frequency f1 at station 1), L 12 (indicating the line loss value of the signal frequency f1 at station 2), L 1m(Indicates the line loss value of signal frequency f1 at station m). Similarly, for signal frequency f2, the corresponding line loss value L is measured. 21 、L 22 、……L 2m And so on.

[0052] For a specific signal frequency, by adding up the line loss values at all stations, the total line loss of the signal frequency is obtained. Dividing the total line loss by the number of stations gives the average line loss of the signal frequency. For example, for signal frequency f1, its total line loss S1 can be expressed as:

[0053] S1 = L 11 +L 12 +…+L 1m (1)

[0054] Then, under the 2G communication system, the average line loss M1 of signal frequency f1 can be expressed as:

[0055] M1 = S1 / m (2)

[0056] Calculate the other signal frequencies under the 2G communication system in turn according to the above method, that is, calculate the total line loss and the average line loss of signal frequencies f2, f3, … fn respectively. Finally, the average line loss of each signal frequency under the 2G communication system can be obtained. Similarly, the average line loss of each signal frequency under the 3G and 4G communication systems can also be obtained by using the above method.

[0057] Step 203: Compare the difference value between the average line loss of each signal frequency under each communication system and the reference line loss value. When the first difference value is greater than the preset first threshold, it is determined that there is an abnormal line loss station. The first difference value is the difference value between the average line loss of any signal frequency under any communication system and the reference line loss value. The reference line loss value is pre-stored in the server. The reference line loss value includes the reference average line loss of each signal frequency under the corresponding communication system.

[0058] In the embodiment of the present application, the reference line loss value is obtained by correcting the line loss values of each signal frequency at all stations under different communication systems, that is, correcting the line loss of the calibration environment during the trial production stage of the terminal device, and storing the corrected line loss values in the server. The reference average line loss is the average line loss of each signal frequency under each communication system calculated according to the corrected line loss values. For example, the reference line loss values under the 2G, 3G, and 4G communication systems can be expressed as: L 2 [a2, b2…n2], L 3 [a3, b3…n3], L 4[a4, b4…n4], where a2, b2…n2 represent the respective signal frequencies in the 2G communication system, a3, b3…n3 represent the respective signal frequencies in the 3G communication system, and a4, b4…n4 represent the respective signal frequencies in the 4G communication system.

[0059] During the mass production stage of the terminal device, after the test equipment obtains the average wire loss value of each signal frequency in the same communication system, it sends the average wire loss value to the server. The server compares the difference value between the average wire loss value and the reference wire loss value. When the difference value between the average wire loss value of any signal frequency in any communication system and the reference wire loss value is greater than the preset first threshold, it is determined that there is an abnormal wire loss position. Here, the preset first threshold is a pre-set judgment standard value. For example, the preset first threshold can be 0.3. The embodiments of the present invention do not make any limitations. It should be noted that in the embodiments of the present application, the difference value can be represented by an absolute value, or a relative value or other methods can be used.

[0060] In some embodiments, the test equipment can directly send the wire loss values of each signal frequency in all positions under multiple communication systems to the server. The server obtains the average wire loss value of each signal frequency in the same communication system and compares it with the reference wire loss value, and determines whether there is an abnormal wire loss position according to the difference value. For example, if the difference value between the average wire loss value of the a2 signal frequency in the 2G communication system and the reference wire loss value in the 2G communication system is greater than 0.3, it is determined that there is an abnormal wire loss position for the a2 signal frequency in the 2G communication system.

[0061] By adopting the above embodiments, the server can automatically identify whether there is an abnormal wire loss position by comparing the difference values between the average wire loss values of each signal frequency in each communication system and the reference wire loss value, thereby effectively avoiding batch quality accidents.

[0062] When the server identifies that there is an abnormal wire loss position, it needs to conduct further comparative analysis to determine the abnormal wire loss position and lock this position. Please refer to Figure 3 , Figure 3 is a flowchart of a method for determining an abnormal wire loss position in an embodiment. As Figure 3 shown, the method may include the following steps:

[0063] Step 301, obtain the wire loss values of the target signal frequency in all positions under the target communication system, where the target signal frequency under the target communication system is the signal frequency corresponding to the first difference value greater than the preset first threshold.

[0064] In the embodiments of the present application, the first difference value represents the difference between the average line loss value of any signal frequency under any communication system and the reference line loss value. When the first difference value is greater than a preset first threshold value, the corresponding signal frequency is the target signal frequency under the target communication system. For example, if the difference between the average line loss value of the a3 signal frequency under the 3G communication system and the reference line loss value under the 3G communication system is greater than 0.3, the line loss values of the a3 signal frequency under the 3G communication system at all stations are obtained.

[0065] Step 302, compare the second difference value between each line loss value and the average line loss value.

[0066] In the embodiments of the present application, the average line loss value is the average line loss value of the target signal frequency under the target communication system among all stations. For the description of the method for obtaining the average line loss value, reference can be made to the above embodiments and will not be elaborated here. By comparing the line loss values of the target signal frequency under the target communication system at all stations with its average line loss value one by one, the server can determine the line loss values with relatively large deviations from the average line loss value among all stations.

[0067] Step 303, when the second difference value is greater than a preset third threshold value, use the station corresponding to the second difference value as the abnormal line loss station.

[0068] In some embodiments, the preset third threshold value is a preset standard value used to judge the deviation between the line loss values of the target signal frequency at all stations and its average line loss value. For example, if the line loss value of the a3 signal frequency under the 3G communication system at station 1 is greater than the preset third threshold value, for example, greater than 0.4, it indicates that the line loss value detected for the a3 signal frequency under the 3G communication system at station 1 has a relatively large deviation from the average line loss value, and the line loss detected at this station may be abnormal. At this time, station 1 is used as the abnormal line loss station. The specific value of the preset third threshold value is not specifically limited in the embodiments of the present application.

[0069] Step 304, after excluding the abnormal line loss stations, obtain the average line loss values of each signal frequency under the same communication system again.

[0070] In some embodiments, after the server determines the abnormal line loss stations, it can send an instruction to the test device. After receiving the instruction, the test device controls the locking of the abnormal line loss stations on the production line of the terminal device, and they cannot be put into production. At the same time, after the server excludes the determined abnormal line loss stations, it obtains the average line loss values of each signal frequency under the same communication system again. The specific method for calculating the average line loss value will not be elaborated here. After excluding the abnormal stations, the distortion of the abnormal line loss values on the average line loss value can be reduced, so as to obtain an average value that more accurately reflects the line loss situation of the normal stations under the same communication system.

[0071] Step 305, when the first difference value is less than or equal to a preset first threshold, it is determined that there is no abnormal line loss station.

[0072] In some embodiments, for the line loss average values of each signal frequency under the same communication system obtained again after excluding the abnormal line loss stations, the line loss average values obtained again are compared with the reference line loss values stored in the server again. If the difference value between the line loss average value of any signal frequency under any communication system and the reference line loss value is less than or equal to the preset first threshold, it indicates that the line loss values detected at the remaining stations after excluding the abnormal line loss stations are all within the normal range, indicating that there are no abnormal line loss stations among the remaining stations. If there is still a situation where the difference value between the line loss average value of a certain signal frequency under a certain communication system and the reference line loss value is greater than the preset first threshold, it indicates that there are still abnormal line loss stations among the remaining stations. Then, the method described in Steps 301 to 305 is executed again until the first difference value is less than or equal to the preset first threshold, and it is determined that there is no abnormal line loss station.

[0073] In some other embodiments, when the second difference value is greater than a preset third threshold, the station corresponding to the second difference value is used as the station with abnormal line loss to be determined. At this time, the station with abnormal line loss to be determined is excluded, and the line loss average values of each signal frequency under the same communication system are obtained again and the difference value from the reference line loss value is calculated. When the difference value is less than or equal to the preset first threshold, the station with abnormal line loss to be determined is determined as the abnormal line loss station.

[0074] By using the above embodiments, the signal frequencies with abnormal line loss stations can be determined through the first difference value, and then the difference between the line loss values of all stations and the line loss average value is further compared at this signal frequency. Through the second difference value, the abnormal line loss stations can be accurately found. After excluding the abnormal line loss stations and repeating the above operations again, it can be ensured that all the abnormal line loss stations are locked and excluded, so that there are no abnormal line loss stations among the remaining stations, thereby effectively reducing the abnormal line loss in the inspection of production line stations and avoiding batch quality accidents in the production line of terminal devices.

[0075] Please refer to Figure 4 , Figure 4 which is a schematic diagram of the overall process of the method for determining abnormal line loss in an embodiment.

[0076] As Figure 4 shown, the overall process of this method may include the following steps:

[0077] Step 401, obtain the line loss values of each signal frequency under multiple communication systems supported by the terminal device to be detected at all stations.

[0078] In the embodiments of the present application, a gold board can be used to check the line loss of the production line environment of the terminal device to be detected. For a specific communication system, the gold board is the main board that is the same as the terminal device to be detected and has been calibrated for power. At the same time, the maximum transmission power values of each transmission path at different signal frequencies under this communication system are stored in the gold board file. In the production link of the terminal device on the production line, the gold board is placed in a fixture for power testing. At this time, the power value obtained from the test reflects the actual transmission power situation of the terminal device under the combination of a specific communication system and the corresponding signal frequency. Subsequently, the measured power value is compared and analyzed with the maximum transmission power value stored in the gold board file at the corresponding frequency band and signal frequency, so as to calculate the radio frequency line loss value measured by the terminal device at the production line position under a specific communication system and a specific signal frequency.

[0079] Step 402: Compare whether the line loss difference value between the same frequencies under different communication systems is less than or equal to a preset second threshold.

[0080] In some embodiments, before comparing the line loss difference values between the same signal frequencies under different communication systems, the line loss anomaly determination method in the present application further includes:

[0081] Compare the difference values between the line loss values of each signal frequency at all positions under multiple communication systems and the reference line loss value. When the difference value is less than or equal to a preset fourth threshold, compare the line loss difference values between the same signal frequencies under different communication systems.

[0082] In the embodiments of the present application, after using the gold board to check the line loss values of different frequencies at all positions under different communication systems, the line loss value data can be stored in the test device. The test device sends the line loss value data to the server. The server can compare the line loss values of different frequencies detected at each position under different systems with the reference line loss value. The reference line loss value includes the average reference line loss of each signal frequency under the corresponding communication system. When the obtained difference value is less than or equal to the preset fourth threshold, further compare the line loss difference values between the same signal frequencies under different communication systems. Among them, the preset fourth threshold is a preset standard value. For example, the fourth threshold can be 0.5, and the embodiments of the present invention do not make specific limitations here. In addition, if there is a difference value greater than the preset fourth threshold in the obtained comparison, re-obtain the line loss values of each signal frequency at all positions under different communication systems.

[0083] In the above embodiments, the difference value may be the difference between the line loss value of any signal frequency at any station position under any communication system and the reference line loss value of the corresponding signal frequency, or the difference between the sum of the line loss values of different signal frequencies at a station position and the sum of the reference line loss values under the corresponding different signal frequencies. For example, under the 2G communication system, the line loss values of different signal frequencies are measured at station position 1. Assume that there are signal frequencies f1, f2, f3, … fn at station position 1, and the corresponding measured line loss values are L1, L2, L3 … Ln respectively. Assume that under the 2G communication system, the reference line loss values corresponding to the signal frequencies f1, f2, f3, … fn are B1, B2, B3 … Bn respectively. If the difference value is represented by the difference between the line loss value of any signal frequency at any station position under any communication system and the reference line loss value of the corresponding signal frequency, then for the signal frequency f1, its reference line loss value is B1, and the difference value of this signal frequency is L1 - B1, and so on. If the difference value is represented by the difference between the sum of the line loss values of different signal frequencies at a station position and the sum of the reference line loss values under the corresponding different signal frequencies, then the difference value at this station position is (L1 + L2 + L3 + … + Ln) - (B1 + B2 + B3 + … + Bn).

[0084] In some embodiments, as an optional implementation manner, the method for comparing the line loss difference values between the same signal frequencies under different communication systems may be to compare the average line loss values of the same signal frequency at all station positions under different communication systems, or to compare the same signal frequency at a single station position under different systems. The specific method for obtaining the average line loss value of the same signal frequency at all station positions under different communication systems is similar to the method for obtaining the average line loss value of the same signal frequency under the same communication system, which will not be elaborated here. Compare the obtained average line loss values between different systems to obtain the difference value, and determine whether the line loss difference value between the same frequencies under different communication systems is less than or equal to a preset second threshold. The preset second threshold is a preset standard value used to determine whether the line loss difference between the same frequencies under different communication systems is obvious. For example, the preset second threshold may be 0.2. Under the condition of meeting the condition, the next step can be carried out. If this condition is not met, that is, when it is greater than the preset second threshold, the line loss values of each signal frequency at all station positions under different communication systems are obtained again.

[0085] Step 403: Obtain the average line loss value of each signal frequency under the same communication system.

[0086] In the embodiment of the present application, in the previous step, the line loss difference values between the same signal frequencies under different communication systems are compared. Under the condition that the difference value is less than or equal to the preset second threshold, the average line loss value of each signal frequency under the same communication system is further obtained and compared with the reference line loss value.

[0087] Step 404: Compare whether the difference value between the average line loss of each signal frequency under each communication system and the reference line loss value is greater than a preset first threshold.

[0088] In some embodiments, for each communication system, the line loss values of each signal frequency at different positions can be obtained separately. Then, the line loss values of the same signal frequency under the same communication system at all positions are summed and divided by the number of positions to obtain the average line loss of the signal frequency under the communication system. And when the difference value between the average line loss of any signal frequency under any communication system and the reference line loss value is greater than the preset first threshold, it is determined that there is a position with abnormal line loss, and then the position with abnormal line loss is further determined according to the method described in the above steps 301 to 303.

[0089] Step 405: Exclude the positions with abnormal line loss corresponding to the second difference value greater than the preset third threshold, and obtain the average line loss of each signal frequency under the same communication system again.

[0090] Step 406: Lock and alarm the excluded positions.

[0091] In some embodiments, the method for determining abnormal line loss in this application further includes:

[0092] When it is determined that there is a position with abnormal line loss, trigger an alarm mechanism. The alarm mechanism includes locking the position with abnormal line loss and sending an alarm prompt message to the engineering personnel. The alarm prompt message is used to remind the engineering personnel to re-check the line loss value of the position with abnormal line loss.

[0093] In the embodiments of the present application, when the server determines that there is a line loss abnormal position, it can immediately send a control instruction to the test device to enable the test device to start the alarm mechanism. Moreover, the server can further send the identification information of the line loss abnormal position to the test device. After receiving the identification information, the test device locks the line loss abnormal position, and the locked position cannot be put into production. At the same time, an alarm prompt message is sent to the engineering personnel in the system to remind the engineering personnel to conduct a check. For example, in the database where the test device stores line loss data, a status field is set for each position. When a line loss abnormal position is detected, the status field of this position is updated to "abnormal lock". In this way, when querying or processing line loss data subsequently, the locked line loss abnormal positions can be quickly filtered out according to this status field. In addition, the line loss abnormal positions can be prominently displayed on the display interface of the test device with special colors (such as red), icons or flashing effects, or an alarm window can be popped up on the interface so that the engineering personnel can immediately see the alarm prompt. The pop-up window can include concise alarm information and operation buttons. The alarm information can include the specific location information of the line loss abnormal position, as well as the historical line loss data of the line loss abnormal position, etc., for the engineering personnel to compare and analyze. The operation buttons on the display interface can be set to "View Details", "Confirm Receipt", etc., to facilitate the engineering personnel to respond quickly.

[0094] By adopting the above embodiments, through comprehensive comparison and analysis of the line losses of different systems and different positions, the line loss abnormal situations can be discovered in time, the accuracy of line loss abnormal judgment is improved, and the quality problems caused by human factors are reduced; after removing the line loss abnormal positions, the line loss average value is recalculated and compared again to ensure the reliability of the line loss data; the line loss abnormal positions are locked and alarmed to prompt the engineering personnel to re-check the line loss, effectively strengthening the quality control of the production line.
